| Abstract: | The following measures to deal with the common failing in bridge construction are discussed. The settlement of soft foundation soil at the end of bridge and the car jumping are brought under control effectively by means of strengthening foundation and light weight material backfilling. The top level of the bridge pov-ement is brought under control accurately with the aid of new construction technique about side form leveling system for bridge surface concreting. The quality of fence for striking protection is improved significantly by means of integrated large-scale steel form technique, The deviation in level for expansion joint installation is brought under control with the aid of expansion joint installating after backward trenching technique. |
